Question

Find the magnitude of a vector, A=2i^-2j^

  1. 3.6
  2. Non-plan 4.2 ar
  3. 2.8
  4. 1.9

hintHint:

Magnitude =|v|=square root of a squared plus b squared end root

The correct answer is: 2.8


    • Suppose there is a vector v= ai^+bj^
    • So Magnitude =|v|=square root of a squared plus b squared end root
    • So |v|=square root of 2 squared plus 2 squared end root= 2.8
